Scrafty
Looks ok but I would use
Drain punch
Crunch
Stone edge
Dragon dance
Crunch gets you stab rest is obvious
Also go 4hp 252atk 252speed
And a item like leftovers muscle band or life orb

Zoroak
Well let's face it it's a mono dark team that makes illusion useless
Though you still have the eloment of supprise
I normally go sp sweeper but I'll do 2sets
Sp set
Nasty plot
Flamethrower
Dark pulse
Extrasensorry
252spatk 252speed
Nasty plot doubles spatk dark pulse gets stab and other to are weekness coverage
Actually I won't make a second set because yours looks ok maybe add uturn

Umbreon
Well that's a decent set plus sets up other Pokemon :)
Invest evs in def and spdef

Honchkrow
Movest looks good but go for a speed + nature never go neutral
Honchkrow has terrible def so you want good speed for decent sweep
Go 252atk 252speed

Hydreigon
I like to go with choice specs 252spatk 252speed timid
Draco meteor
Dark pulse
Flamethrower
Dragon pulse or u turn
Draco meteor does great paired up with specs and good spatk

Darkrai
I would go wise glasses or life orb
252spatk 252speed
Modest
Dark void
Dream eater
Nasty plot
Dark pulse
That is the set I used when I had a ubers team on po and it worked great put them to sleep raise your spatk a few times then dark pulse
